It's called a seismograph. I just finished learning about that in Science class.
seismograph
instrument that respond to ground motions such as caused by earthquakes, volcanic eruptions and explosions
They can detect ground movements as small as one hundred- millionth of a centimeter ^^^ Got that answer from my science book, so it's surely 100% correct. (:
surface waves produces the most severe ground movement because its on the surface of the earth

seismograph
A seismograph is an instrument used to measure and record vibrations and movement in the Earth and on the ground. These instruments are no longer as widely used, as there are modern instruments used to separately measure or record these movements, such as seismometers.

a measuring instrument for detecting and measuring the intensity and direction and duration of movements of the ground (as an earthquake)
